2.film history Flashcards
What is Film (As a physical object)
a thin flexible material coated in light sensitive emulsion that retains an image after it’s exposed to light
How long does an image stay in your brain after it’s gone.
1/5 of a second.
what is the phi phenomenon and who created it
defined in 1912 by the Czech born psychologist Max Wertheimer .an optical illusion that lets you see a series of images in rapid succession as continuous motion
what are zoetropes
bowl or deep cylinder with sequential images painted on the inside and small slits for windows cut into the edges. spin the bowl and peer through the slits and thanks to persistence of vision and the phi phenomenon the pictures seem to move. this device has many different variations and names
What is the camera obsura
a box, tent or room with a lens or pinhole in one end and reflective surface like a mirror at the other light travels through the hole and displays an inverted image on the mirror. means dark chamber in latin, which means camera means chamber.
how were pre camera technologies thought of?
Devices like the the zoetrope and camera obsura were thought of as novelties and toys
Who took the first known camera photograph? How did he do it?
French inventor, Joseph Nicephor Niepce , took the first photo ;view from the window at le gras. used a camera obscura to project an image onto a pewter plate coated in a light sensitive chemicals. the areas of the chemical that were hit with the brightest light hardened but the area that is touched by weaker light could be washed away so crude permanent record of the original image survived. How ever it would take a couple of days to show up.
Who made the process of taking photographs more efficient after the first photograph was taken? How?when?
Louis Daguerre, Niepce’s friend was able to shorten the exposure time to a few minutes. this became the first mass market means of taking photographs in 1839
what were the problems with Daguerre’s photography method?
The photos were fragile, difficult to replicate, and the chemicals were toxic
Who was the third man to revolutionize photography
George Eastman an American entrepreneur and founder of Eastman Kodak who invented a way of taking pictures on paper rather than metal or glass plates this method also didn’t need as many chemicals.
What began the phenomenon of motion studies. When?
In 1872 Leland Stanford the former governor of California and horseracing aficionado made a bet that a horse at full gallop raises all 4 hooves off the ground at some point. to settle the bet Stanford commission a photographer an inventor named Edward Muybridge to find photographic proof so Muybridge set up of 12 cameras along a racetrack each triggered by a tripwire to capture a still image of a horse in motion
What is the chromophotographic gun and who invented it
the chromophotographic gun used sheets of photographs instead rolls,so it could take 12 pictures a second
Invented by Etienne Jules Morais captured birds in flight and athletes in motion.
What was the zoopraxiscope?
a device to show images in succession, made by Edward Muybride the same guy that took the pictures at the horse race
What was the Kinetograph
The world’s first motion picture camera, made by Thomas Edison and his employee W.K.L Dickson
